iii INTRODUCTION
Elephant Butte Dam (originally called Engle Dam) was one of the first major structures built by the Reclamation Service (now the Bureau of Reclamation) after its formation in 1902. Construction of the dam began in 1908, but progress was delayed when difficulty was encountered in obtaining reservoir land. Construction of the dam resumed in 1912 and was completed in 1916, although water storage operations began in January 1915. Located about 125 miles north of El Paso, Texas, on the Rio Grande, the dam is part of the multipurpose Rio Grande Project that controls floods, generates power, and stores and delivers irrigation water. The dam is a 301-foot-high concrete gravity structure that is 1,674 feet long and impounds 2,110,298 acre-feet of water. The spillway is an uncontrolled concrete ogee weir structure. A spillway channel below the dam was added in 1921 and modified in 1947. Service outlet deflectors were added in 1944. The general plan and sections of the dam and spillway are shown in figure 1 1/. In 1915, the surface area of Elephant Butte Reservoir was 40,064 acres and the capacity was 2,634,800 acre-feet at a spillway crest elevation of 4,407 feet 2/. The 1980 survey showed a surface area of 36,897 acres and a capacity of 2,110,298 acre-feet at the same spillway crest elevation. This difference indicates a loss of 524,502 acre-feet in capacity in the 65.1 years since the dam was built. The reservoir has a length of 41 miles and an average width of 1.39 miles. The average width was determined for the entire reservoir including the portion known as "The Narrows" which separates the upper and lower reservoir areas. The total Rio Grande drainage area above the dam is 25,923 square miles, of which 11,803 square miles are the net sediment contributing area. Sediment from the remaining drainage area is being trapped by upstream dams such as Abiquiu, which closed in 1963; Galisteo, closed in 1970; and Cochiti, closed in 1973. A plot of monthly inflows to the reservoir is shown in figure 2 for the period January 1916 through June 1980. The average annual inflow, based on 63.3 years of record, is 845,300 acre-feet. An inflow-duration curve based on the monthly inflow discharge is shown on figure 3. Information from curves of this type is useful in making reservoir operation studies. Stream- flow records of the gaging station at San Marcial, New Mexico, were used to represent the inflow for the period through water year 1951. Beginning with water year 1952, the combined streamflow records of the floodway and convey- ance channel at San Marcial were used. These records, however, did not reflect the total inflow since additional downstream tributaries to the reservoir, such as Monticello and Nogal Canyons, also contribute to the inflow.
1/ All figures and tables follow the text. 2/ All elevations quoted are based on the original project datum. To adjust the elevations to mean sea level datum, 43.3 feet should be added. Monthly outflow records were plotted on figure 4 for the period October 1916 through September 1980 (63.9 years). An average annual outflow of 701,400 acre-feet was computed for this period. Reservoir stages at the end of each month from March 1915 through January 1980 are plotted on figure 5. Elephant Butte Reservoir operation ranged from a minimum elevation of 4,258.03 feet in 1954 to a maximum elevation of 4,409.15 feet in 1942.
SUMMARY AND CONCLUSIONS This report includes a discussion of methods used to measure and study 65.1 years of reservoir sediment accumulatiofts. It also briefly describes the field surveying procedures and equipment.
The primary purpose of running the 1980 survey was to gather data needed to compute the capacity of Elephant Butte Reservoir as required by the Rio Grande Compact.
Standard land surveying methods were used to establish horizontal control points for the survey. The hydrographic survey used sonic depth recording equipment and an automated survey system with a line-of-sight electronic positioning unit. The system continuously recorded reservoir depths and horizontal distances from a fixed point as the boat was steered across the range line. Reservoir water surface elevations read on the gage at the dam were used as control in converting sonic depth measurements to true bottom elevations and to delineate the cross-sectional profiles.
The capacity of the reservoir from the 1980 survey was determined to be 2,110,298 acre-feet, with a surface area of 36,897 acres at a spillway crest elevation of 4,407 feet. The reservoir area and capacity tables were produced by a computer program which used measured contour surface areas and a curve-fitting technique to compute both area and capacity at prescribed elevation increments.
A comprehensive summary of the reservoir sediment data for the 1980 survey is contained in table 2. The volume of sediments that have accumulated in the reservoir since the original survey amounted to 524,502 acre-feet, indicating a loss in capacity of about 20 percent. An average annual sediment accumula- tion rate of 8,057 acre-feet was found for the period from 1916 to 1980. The sediment yield rate from the drainage area was 0.311 acre-foot per square mile per year for the same period.
DESCRIPTION OF BASIN
Topography of the drainage area is varied. In the extreme northern portion, it is mountainous and rugged. South of Santa Fe, New Mexico, the topography is less rugged, consisting of isolated mountains separated by desert plains and the Rio Grande Valley. The elevations of the drainage area vary from 12,000 feet above mean sea level at the Continental Divide to 4,450 feet above mean sea level in the reservoir headwaters area.
2 The higher elevations are forested with pine and fir trees, and the slopes are sprinkled with cedars along the foothills. Natural cover of the plains consists chiefly of creosote bush, sagebrush, greasewood, cactus, and natural grasses. Thick stands of salt cedars, willows, and cottonwoods grow along the riverbanks above the reservoir. The Rio Grande begins in the San Juan Mountains of Colorado and flows between the Conejos Mountains and La Garita Hills. Stream channel slopes are steep in the mountainous headwater regions. Most of the surface rock in these regions is igneous or metamorphic and not easily eroded. Just above the New Mexico State line, the river enters a deep canyon flowing through a stretch of low sediment contribution until it enters Espanola Valley near the confluence with the Rio Chama. Upon leaving the valley, it enters White Rock Canyon in the vicinity of Otow Bridge. The unconsolidated sediments of the Santa Fe Formation (Miocene and Pliocene continental deposits) have been eroded to form the valley of the Rio Grande from the lower end of White Rock Canyon near Cochiti Diversion Dam to near San Acacia. The flood plains and terraces of the valley are composed of alluvium that is available for trans- port and contributes substantial quantities of sediment to the Rio Grande. From the mouth of the Rio Salado, just upstream from San Acacia, to the head- waters of Elephant Butte Reservoir, the Palomas Formation of the Quaternary period has been eroded to form the river valley. The major geologic forma- tions of the Rio Grande Valley are of the Cenozoic era.
SURVEYS AND EQUIPMENT Nine different surveys were conducted previously, beginning in 1916. The 1925, 1935, 1940, and 1957 surveys were run by the contour method, while the range method was used for the 1947, 1969, 1974, and 1980 surveys. Fieldwork for the 1980 survey began in June 1979 and ended January 24, 1980. A layout of the reservoir sedimentation range system is shown in figure 6.
Surveyinq Methods The fieldwork consisted of locating the existing sedimentation range end markers and relocating those which had been lost or destroyed. To prepare for the range line survey, an extensive line clearing progrn was conducted in the reservoir area above the Narrows. Range lines 41 through 61 and portions of 40, 37, and 36 were not cleared because of high ground water or surface water. To develop range end control for the 1980 hydrographic survey, a traverse was surveyed from Range 85 through Range 50 and tied into a triangulation point at Range 38 west. Precise electronic distance measuring equipment that could be interfaced with a digital computer to process the data was used for this traverse work. Control points established by the traverse facilitated the profiling of inundated ranges by the sonic sounding equipment described in the following paragraph. Results of the old traverse established for previous surveys were used for control points in running the 1980 survey for ranges in the reservoir area upstream from Range 50. The above water portion of most existing range lines was profiled from the range end to water's edge using standard land surveying procedures and equipment.
3 A hydrographic survey was run in January 1980, using sonic depth recording equipment to sound the underwater portion of 45 range lines. A depth recorder was interfaced with an automated positioning system (fig. 7) to give continuous reservoir depth and sounding position as the sounding boat traversed each range line. The positioning system transmitted a line-of- sight, microwave signal to fixed shore stations (fig. 8), and converted the time of reply to range distances, which were then used to compute the coordinate position of the sounding boat. The controls required for the system included reservoir elevation, horizontal grid coordinates for all range ends and fixed shore stations, and the elevations of the shore station antenna. Upon activating the system, the boat (fig. 9) was steered across the range line at a velocity of 8 feet per second. The system also gave directions to the boat operator for maintaining course. During each run, the depth and position data were recorded on magnetic tape for later processing on an electronic computer. A graph plotter was used to track the boat and to give an immediate plot of each range profile. Auxiliary field equipment included radios for communication between shore and boat personnel and another boat to move equipment and personnel around the reservoir. A "cutting in" or triangulation procedure was used to resurvey 15 ranges in the area beginning with Range 60 on upstream through the Narrows.
RESERVOIR SEDIMENT DISTRIBUTION Lonqitudinal Distribution
The longitudinal profiles were plotted for the original, 1969, and 1980 reservoir conditions (fig. 10). Longitudinal profile data were also plotted in dimensionless form (fig. 11) for the original and 1980 conditions relating percent of depth to percent of distance. Percent of depth was computed as the ratio of the thaiweg depth at each range to the total depth. Thaiweg depth was computed as a difference between the thalweg elevation (lowest point) at a section and the lowest point on the profile (elevation 4,210). Total depth, 197 feet, was taken as the difference in lowest point on the profile (elevation 4,210) and the spiliway crest elevation 4,407. Percent of distance was computed as a ratio of the distance between the dam and each range to the total distance 41.33 miles measured between the dam and the point where the longitudinal profile intersects the thaiweg elevation 4,407 upstream. The graph on figure 10 indicates that between the 1915 and 1980 surveys, sediments had deposited longitudinally to depths shown below:
Interval distances above dam Average depth of sediment (miles) (feet) 0-8 30 8-11 38 11-14 46 14-16 54 16-20 44 20-29 21 2 9-38 15 38-41 5
4 The greatest depths of longitudinal sediment deposits occurred between 14 and 16 miles above the dam. This reflects a morphological effect that the Narrows region has on sediment deposition. The Narrows has an average width of 0.36 mile compared to the average width of 1.39 miles for the total reservoir.
As a matter of further practical interest, a theoretical distribution of sediment within the reservoir was computed using the Empirical Area-Reduction Method [1]*. It was assumed that the sediment inflow volume to be distri- buted would be 524,502 acre-feet, the volume measured by the 1980 survey. A plotting of the depth-capacity relationship (fig. 12) using the original data indicated the reservoir to be type II. Results of the sediment distribution computations are listed in columns (8), (9), and (10) of table 1 for a type II reservoir. These computations predicted the sediment would reach an elevation of 4,259.4 feet by 1980. This estimate compares favorably to the elevation of 4,234 feet determined from the 1980 survey. The sediment distribution curves on figure 13 show how the actual distribution compares with the theroretical distribution of a type II reservoir. The curves show percentages of depth plotted against sediment deposited. The greatest differences between the actual and type II curves are in the 60 to 80 percent depths. Using the end-of-month data (fig. 5), a stage-duration curve (fig. 14) was derived. This type of curve has a twofold use: (1) classifying the reser- voir for sediment distribution computations, and (2) predicting the delta formation of a reservoir [1]. For delta computations, data from the curve are used to determine the pivot point (where the topset and foreset beds intersect). Using the 50 percent duration as a mean, the curve shows an end-of-month elevation stage of 4,337 feet. This indicates the pivot point occurs at Range 60 as seen in the longitudinal profile (fig. 10). For a sediment distribution study, the end-of-month stage of 4,337 feet indicates the reservoir is operated with a normally moderate to considerable reservoir drawdown. This would classify the reservoir as a type II (flood plain- foothill) reservoir as indicated by the depth-capacity curve (fig. 12).
Lateral Distribution Ground profiles of the 75 reservoir sedimentation ranges are shown on figures 15 through 89. The profiles illustrate the general lateral distribution of sediments in the reservoir. The orignal and 1980 profiles do not fully agree in the lateral direction for all ranges. The original profiles were transcribed from a 1915 topographic map with a contour interval of 10 feet. Thus, the point locations from the 1980 survey were of much higher accuracy than the location of points read from the 1915 topographic map. Also, it was necessary to estimate a portion near the end of some profiles to show how the original survey data connect with the 1980 data and to facilitate the reservoir area computations.

5 SEDIMENT ANALYSES Sediment Accumulation
Sediments have accumulated in Elephant Butte Reservoir to a total volume of 524,502 acre-feet since the dam was constructed over 65 years ago. An average annual accumulation rate of 8,057 acre-feet was computed for the 65.1-year period. The net sediment accumulation rate from the contributing basin was 0.311 acre-foot per square mile per year for the same period. Reservoir Sedimentation Survey
A summary of the reservoir sediment data for the 1980 survey is contained in table 2. The data include a tabulation of incremental sediment inflow volume and sediment accumulation computed for the periods between the original (1915) and the 1957, 1969, and 1980 surveys. Both types of data are valuable in practical and research studies.
RESERVOIR AREA AND CAPACITY The 1980 reservoir surface areas were computed by the Width Adjustment Method described by Pemberton [2]. Briefly, the method used entails computing the 1980 contour areas between any two ranges by applying an adjustment factor to the 1915 contour area between the two ranges. The adjustment factor was determined as a ratio of the new average width to the original average width for both the upstream and downstream ranges at a specified contour. Computa- tions were facilitated by subdividing the reservoir into segments using the sedimentation range lines to delineate the limit of each segmental boundary. For any given contour elevation, the 1915 surface areas were multiplied by the adjustment factor to compute the 1980 surface area of each segment. The total surface area at a given contour elevation was computed as the summation of all segmental areas at that elevation.
The 1980 surface areas were used as control parameters for computing the reservoir capacities by electronic computer. The program procedure included computation of 0.01- to 1-foot area increments by linear interpolation between 10-feet contour intervals. The progressive computational procedure began by testing the initial capacity equation over successive intervals to determine whether it was within an allowable error limit (0.0001 in this case). This capacity equation was then used over the whole range that fit within the allowable error limit. For the next interval, beginning where the initial allowable error limit was exceeded, a new capacity equation (integrated from the basic area equation over that interval) began testing the fit until the limit was exceeded. Thus, the capacity curve was defined by a series of curves or splines, each falling within a specific elevation interval as constrained by the limiting error. The final area equations were subsequently derived by differentiation of the capacity equations. Capacity equations are of second order polynomial form:
6 y = a1 + a2 x + a3
where: y = capacity x = elevation above an elevation base ai = intercept a and a = coefficients
Results of the 1980 area and capacity computations are listed in columns (4) and (5) of table 1. Listed in columns (2) and (3) of this table are the original area and capacity values. A special set of area-capacity tables has been published separately for the 0.01-, 0.10-, and 1-foot elevation increments [3]. Both the original and 1980 area-capacity curves are plotted on figure 90. At spillway crest elevation 4,407, the 1980 capacity is 2,110,298 acre-feet and the surface area is 36,897 acres. During the course of the area and capacity computations, it was discovered that the capacity had increased in some segments of the reservoir since the last complete survey in 1969. These gains in capacity were attributed in part to the effects of compaction of sediments in those segments. An additional factor influencing the increased capacities was the precision used to measure the profiles during the 1980 survey. The 1915 profiles were measured from the original topographic map (contour interval, 10 feet). As a result, the apparent profile width changes indicated between the 1915 and 1980 surveys were, in many instances, due to inaccuracies in the original profile data. BIBLIOGRAPHY

Figure 90. - Area-capacity Curves - Elephant Butte Reservoir Mission of the Bureau of Reclamation
The Bureau of Reclamation of the U.S. Department of the Interior is responsible for the development and conservation of the Nation's water resources in the Western United State&
The Bureau's original puipose "to provide for the reclamation of arid and semiarid lands in the West" today covers a wide range of interre- lated functions. These include pro v/ding municipal and industrial water supplies; hydroelectrIc power generation; irrigation water for agricul- ture; water quality improvement; flood control; river navigation; river regulation and control; fish and wildlife enhancement; outdoor recrea- tion; and research on water-related design, construction, materials, atmospheric management, and wind and solar power.
Bureau programs most frequently are the result of close cooperation with the 11.5. Congress, other Federal agencies, States, local govern- ments, academic institutions, water-user organizations, and other concerned groups.
A free pamphlet is available from the Bureau entitled "Publications for Sale." It describes some of the technical publications currently available, their cost, and how to order them. The pamphlet can be obtained upon request from the Bureau of Reclamation, Attn 0-922, P 0 Box 25007, Denver Federal Center, Denver CO 80225-0007.
